Grout Penetrability

Abstract: The ability of a grout to penetrate a formation is always a selection requirement for projects in which fracturing is undesirable. The major grout properties affecting penetrability are grain size (for suspended-solids grouts) and viscosity (for true solution grouts). This paper summarizes the comparative positions of common commercial grouts with respect to each other, and suggests a modification in the manner in which comparative data is presented.
